Abstract
A imager has an array of photodetectors, each of which accumulates charge during an integration period as a result of light detected during said integration period, said array having a charge capacity which increases during the integration period. A charge capacity controller coupled to said imager adjusts how the imager increases the charge capacity of the array based upon the brightness distribution detected by said imager during at least one previous integration period.
